This bit is reserved for future use and should always be equal to 0.
These read/write bits can be used to enable/disable functions within
the MCU. Reset loads CONx from EENVR2 to EEACR2.
This one-time programmable bit can be used to protect 16 bytes
($8F0–$8FF) from being erased or programmed.
These read/write bits select blocks of EEPROM array from being
programmed or erased. Reset loads EEBP[3:0] from EENVR2 to
EEACR2.
